November 2024 performance summary across multiple repos (sanity-io/sdk, sanity-io/sanity, sanity-io/client, sanity-io/locales, getsentry/sentry-javascript, denoland/deno). Delivered a set of cross-repo features and stability improvements that strengthen security, reliability, and developer velocity while clarifying business value. Key outcomes include delivering a Kitchensink React SDK Testing App with Vite and sdk-core/sdk-react aliases to demonstrate and validate SDK capabilities in a React environment; enforcing package privacy to prevent unintended external usage; consolidating platform stability and developer experience improvements (WeakMap-based identity for stores, centralized ESLint rules, and Vitest-based testing enhancements) for more predictable builds and faster iteration; fixing localization namespace usage in the Create flow to ensure correct localization strings load; and implementing strict image upload type validation to prevent unsupported formats from being processed. Collectively, these changes reduce risk, improve test stability, and accelerate delivery across the SDK and ecosystem, with ongoing gains in build reliability, security, and DX.
